I Love YTtalk
And I recommend targeted subreddits if you want to try to "promote"...but ultimately, it shouldn't be about promoting. It should be about sharing relevant, quality content...where some (but not all or even most) of your links just *happen* to be your own stuff
I agree with all of the last post. And that last part is what Reddit is all about. It's why self promotion is not a good idea in general. It's not built to be a place for self-promotion. It just isn't. If you manage to make it work for you, then fine. But it's really not what the site is for.
